Proving Loss of Earning Capacity: Admissibility of Evidence in Philippine Law

In a 2016 ruling, the Supreme Court clarified a crucial point in Philippine tort law: how heirs can prove a deceased victim's loss of earning capacity. The case of Enriquez v. Isarog Line Transport, Inc. (G.R. No. 212008, November 16, 2016) reaffirmed that while documentary evidence is generally required, a document not objected to by the defense is deemed admitted and may be used to compute damages. This ruling provides practical guidance for families seeking compensation after a loved one's death.

The Case: A Fatal Bus Collision

Sonny Enriquez, a 26-year-old security guard, was a passenger on an Isarog Line bus in July 1998 when it collided with another bus in Pagbilao, Quezon. Sonny died in the accident. His parents sued the bus companies and their drivers for damages.

The Regional Trial Court (RTC) ruled in favor of the parents, awarding them over ₱1 million for Sonny's "unrealized income" (loss of earning capacity), plus moral and exemplary damages. The Court of Appeals (CA) deleted the unrealized income award, reasoning that the certification from Sonny's employer, ASLAN Security Systems, Inc., had no probative value because the signatory was not presented in court to testify.

The Issue: Proving Income Without a Witness

The sole issue before the Supreme Court was whether the parents were entitled to ₱1,038,960.00 for their son's loss of earning capacity, despite the employer's representative not testifying.

The Ruling: Unobjected Evidence is Admitted

The Supreme Court reversed the CA and reinstated the RTC's award. The Court held that the certification from ASLAN—stating Sonny earned ₱185.00 per day—was admissible because the defense never objected to its presentation during trial.

Key principle: Evidence not objected to is deemed admitted and may be validly considered by the court. The Court distinguished this case from earlier rulings where claimants relied only on self-serving testimony without any documentary support. Here, the parents presented actual documentary evidence—the employer's certification—which was sufficient.

The Formula for Computing Damages

The Supreme Court applied the standard formula for net earning capacity:

Net Earning Capacity = Life Expectancy x Gross Annual Income - Living Expenses

Where:

• Life expectancy = 2/3 (80 - age at death)
• Gross Annual Income = Daily wage x working days per week x weeks per year
• Living expenses = 50% of gross annual income

For Sonny:

• Life expectancy = 2/3 (80 - 26) = 36 years
• Gross Annual Income = ₱185.00 x 6 days x 52 weeks = ₱57,720.00
• Living expenses = ₱28,860.00
• Net Earning Capacity = 36 x ₱28,860.00 = ₱1,038,960.00

Legal Basis

Under Article 2206 of the Civil Code, the heirs of a person killed through a crime or quasi-delict are entitled to indemnity for loss of the deceased's earning capacity. This compensation is not for actual lost earnings but for the loss of capacity to earn—a form of actual damages requiring competent proof.

The Court also reiterated the exceptions where documentary evidence may not be required: (1) when the deceased was self-employed earning less than minimum wage, or (2) when the deceased was a daily wage worker earning below minimum wage, where judicial notice may be taken that no documentary evidence exists.

Practical Takeaways

• Documentary evidence matters. An employer's certification, payroll records, or similar documents are the best evidence of income. Keep these records accessible.
• Object or lose the right. If a party fails to object to evidence during trial, that evidence is deemed admitted and can support a judgment.
• The formula is standard. Courts use the life expectancy formula (2/3 of the remaining years to age 80) and deduct 50% for living expenses to compute net earning capacity.
• Interest accrues. The award earns 6% interest per annum from the finality of the decision until fully paid, pursuant to Bangko Sentral ng Pilipinas Circular No. 799 (2013).
• Exceptions exist for low earners. Self-employed or daily wage workers earning below minimum wage may prove loss of earning capacity even without documentary evidence.
